膨润土是一种高膨胀粘土矿物的名称来自于位置的第一个商业存款，在布雷顿堡，怀俄明美国mineralogically ，膨润土主要由蒙脱石结合各种矿物杂质，如长石，方解石，石英等蒙脱石属于该组的蒙脱石粘土，其中也包括类似的表现，矿物质等beidellite ，皂石和hectorite 。 <br>膨润土地质结构主要是火山岛，大多数商业存款则是由水解或变质的火山岩或火山灰，并almostly发现无处不在，世界<br>该蒙脱石的结构基本上是三层结构与八面体羟基铝板之间夹在两层硅氧四面体。但是，铝原子部分取代取代要么镁或铁原子，从而产生一种电荷不足的单元结构。这个结果在一个小的负电荷对基底平面的二氧化硅四面体是均衡吸收的可交换性阳离子之间相邻的血小板。在天然蒙脱石，这些阳离子通常是钙，钠或镁据该编队的膨润土<br> <br>答：铸造（房协25081000膨润土的锂/钠/钙） <br> B组：冶金（冶金球团粘结剂）房协25081000 <br> C组：钻井泥浆（空气污染指数

Bentonite is a high swelling clay mineral whose name was derived from the location of the first commercial deposits mined at Fort Benton, Wyoming U.S.A. Mineralogical; bentonite mainly consists of montmorillonite in combination with various mineral impurities such as feldspars, calcite, silica, etc. Montmorillonite belongs to the smectite group of clays which also include similar behaving minerals such as beidellite, saponite and hectorite.

Geologically bentonites are mainly of volcanic origin; the majorities of commercial deposits were formed by the hydrolysis or metamorphism of volcanic rock or ash and are almost found in everywhere in world.

The structure of montmorillonite is fundamentally a three-layer structure with an octahedral aluminum hydroxyl sheet sandwiched between two layers of silicon- oxygen tetrahedral. However, the aluminum atoms are partially replaced by the substitution of either magnesium or iron atoms, thereby creating a charge deficiency within the unit structure. This results in a small negative charge on the basal plane of silica tetrahedral, which is balanced by absorption of exchangeable captions between adjacent platelets. In natural montmorillonite, these captions are usually calcium, sodium or magnesium according to the formations of bentonite.
